    • Architecture that includes a multimodal graph modeling and computation system employed in a search framework. The framework utilizes entities to diversify and explore the results page. The multimodal graph modeling paradigm can include web modeling by way of a click graph, a web graph, a social graph, a geospatial graph, and an entity graph, for example. These graphs are then joined based on common properties such as links, clicks, and document entities. Computation can then be performed over the joined graphs to generate a related entity list and a related page list. These lists are then processed by a recommendation engine to provide recommendations to the user.
